Which of the following numbers will replace the question mark (?) in the given series?
168, 191, 218, 249, 284, ?
Detailed Solution & Logic
Correct Answer:
323
Given series:
168, 191, 218, 249, 284, ?
Step 1: Find differences
191 − 168 = 23
218 − 191 = 27
249 − 218 = 31
284 − 249 = 35
So the pattern of differences is:
23, 27, 31, 35
This is increasing by +4 each time.
Step 2: Find next difference
Next difference = 35 + 4 = 39
Step 3: Add to last term
284 + 39 = 323
Final Answer:
323
